The Haddonfield High School rain gardens were installed to beautify the site and to intercept, treat, and infiltrate stormwater runoff from the surrounding sidewalks.

These rain gardens are part of the Cooper River Watershed. The Cooper River watershed is characterized by extensive residential and commercial development and as a result its streams are severely impacted by increased stormwater runoff. To address the water quality issues associated with increased stormwater runoff, demonstration projects like these rain gardens are essential.
